Folly, Earthlings! Folly. It's a mistake to imagine one half of a judgment pair exists to undermine the other. Instead, neither judgment can exist without the other. We can talk of times when a person makes unconscious choices but we can't talk of some function as if it is its products. Te does not exist without Fi in the sense that there is no objective reason to value truth unless one cares for it. (Or something like that.) Likewise, Ti apparently cannot exist unless there is something "out there" to care about.

But why is this so, and what's its relevance to fakery must wait upon a non-phone post, or on someone willing to see cognition as cognition.

Its not that one exists to undermine another. its that undeveloped unconscious(undifferianted) functions have unconscious guiding effect to developed conscious ones. after function has been differentiated, its brought onto conscious control, thus it loses its unconscious guiding effect to other functions.

The whole point is to separate the parts in order the whole to function properly without any unconscious guidance which might lead to unwanted consequences.

When you are guided by your unconscious, you are bound to your fate, but when you take the unconscious to consciousness, you are creating your own future.
